れているものもある。 Among the various recording methods currently known, it is a non-impact recording method that generates almost no noise during recording, is capable of high-speed recording, and can record on plain paper without the need for special fixing processing. The so-called inkjet recording method is recognized as an extremely useful recording method. Regarding inkjet recording methods, various methods have been proposed so far, some have been improved and commercialized, and efforts are still being made to put them into practical use. .

度な技術を要すると共に、その分散安定性を高め
ることは、非常に困難なものである。 The ink used for this purpose is basically composed of a dye and its solvent, and the physical properties of the ink largely depend on the inherent properties of the dye. Therefore, when inkjet recording is conventionally performed using ink containing mainly water-soluble dyes, the resulting ink images are affected by the physical properties of the water-soluble dyes, and their water resistance and light resistance vary. It had the disadvantage of being inferior. Furthermore, the storage stability of ink itself containing such water-soluble dyes is not particularly high. Therefore, recently, attempts have been made to apply pigment-based inks to inkjet recording systems instead of such dye-based inks. This pigment-based ink has the advantage that the light fastness and water resistance of the obtained ink image are extremely good compared to images made using the dye-based ink. However, since the pigment is insoluble in the ink medium, a sophisticated technique is required to finely disperse it in the ink, and it is extremely difficult to improve its dispersion stability.

量の範囲として、約1000〜100000が望ましい。 In the above polymer, the ratio of monomer units forming hydrophilic structural parts is particularly important. In other words, when the weight ratio of monomer units forming hydrophilic structural moieties such as carboxyl groups, sulfonic acid groups, or sulfuric acid ester groups exceeds approximately 40% by weight, the adsorption of the polymer to pigment particles decreases. Deteriorates the dispersion stability of pigment particles. On the other hand, when the amount is less than 2% by weight, the solubility of the polymer itself in the aqueous liquid decreases, and the polymer coagulates or precipitates in the aqueous liquid together with the pigment particles. Therefore, a more preferable ratio of the hydrophilic structural portion in the above polymer is considered to be about 25 to 40% by weight. Also, if the molecular weight of this polymer is too low, it will not contribute to the dispersion stability of the pigment particles, and conversely, if the molecular weight is too high, it will increase the viscosity of the ink itself too much (for example, 20 cps).
(above). Therefore, the molecular weight range of this polymer is preferably about 1,000 to 100,000.

らかにし、本発明をなすに至つた。 Here, as a result of various experiments, the present inventor found that the ratio of the molecular weight W 1 of the pigment to the average molecular weight W 2 of the polymer
It has been found that there is a close relationship between W 1 /W 2 and the stability and driving frequency response of the dispersion. In other words, we prepared and investigated various dispersions with different molecular weights of pigment and polymer, and found that when the above ratio W 1 /W 2 was in the range of approximately 1/2 to 1/150. It was revealed that the stability of the dispersion liquid and the driving frequency responsiveness during ejection are good, and that the driving frequency responsiveness tends to decrease as the dispersion deviates from this, and the present invention has been completed.

If the upper limit of this range is exceeded, there are disadvantages such as a decrease in the color density of the ink and an inability to maintain the viscosity of the ink at an appropriate value. Moreover, when it is less than the following lower limit, the dispersion stability of pigment particles becomes poor.
